Post-Ablation Cavity Evaluation Clinical Study Published in the Journal of Minimally Invasive Gynecology

Study Shows Long-Term Uterine Cavity Access After Water Vapor Endometrial Ablation

Sunday, March 7, 2021

Today AEGEA Medical announced publication of the Post-Ablation Cavity Evaluation (PACE) clinical study in the Journal of Minimally Invasive Gynecology. The PACE study evaluated hysteroscopic access to the uterine cavity for women who previously underwent endometrial ablation for heavy menstrual bleeding as part of a pivotal trial of the company’s Mara™ Water Vapor Ablation System. Additionally, the study assessed the projected feasibility of minimally invasive diagnostic and therapeutic interventions and evaluated the potential correlation between ease of long- term access to the uterine cavity and menstrual bleeding status more than four years after the water vapor ablation treatment. The published study can be found here.

Data for the PACE study were collected from 70 patients at eight centers in a prospective, multi-center, international, observational study designed to evaluate long-term hysteroscopic uterine cavity access in subjects who had completed 36-month follow-up in the pivotal trial. The study was first conducted at seven U.S. sites, followed by a second cohort enrolled at one site in Mexico. A qualified/expert, blinded independent reviewer was utilized to provide an assessment of the uterine cavities.

“The PACE study findings should give physicians confidence in both the short- and long-term benefits of water vapor endometrial ablation,” said Dr. D. Alan Johns, Medical Director, Baylor Research Institute, Fort Worth, and Principal Investigator for PACE. “Publication in a prestigious journal like JMIG increases our clinical community’s awareness of the importance of long-term uterine cavity access post-ablation.”

In addition to the JMIG publication, three leading investigators will present on this important clinical research at the upcoming AAGL (American Association of Gynecologic Laparoscopists) meeting in Vancouver, B.C. The following abstracts will be presented on Monday, November 11, 2019, during the meeting:

  1. There is No Correlation Between Long-Term Hysteroscopic Access to the Uterine Cavity and Menstrual Bleeding Status Following Use of Water Vapor Ablation To Treat Heavy Menstrual Bleeding – Presenter: Dr. JoséGerardo Garza Leal
  2. Long-Term Bleeding Status and Hysteroscopic Cavity Access Results Following Water Vapor Endometrial Ablation for Heavy Menstrual Bleeding in Subjects Who Have Large Cavities, Uterine Myoma and/or Intratubal Contraceptive Inserts – Presenter: Dr. David Levine
  3. Post-Ablation Cavity Evaluation: A Prospective, Multicenter, Observational Study to Assess Hysteroscopic Evaluation of the Uterine Cavity in Subjects Who Have Undergone Water Vapor Endometrial Ablation for the Treatment of Heavy Menstrual Bleeding – Presenter: Dr. Cindy Basinski

AEGEA’s Mara Water Vapor Ablation Treatment is the first FDA-approved endometrial ablation procedure for heavy menstrual bleeding that is specifically designed for use in the doctor’s office without the need for general anesthesia. By utilizing the naturally expansive properties of water vapor, Mara safely and effectively treats patients with a wider range of uterine anatomies than alternative endometrial ablation treatment options. One year after treatment in the pivotal trial, 79 percent of patients met the primary endpoint of the study with a PBLAC score of ≤ 753, 99 percent of patients experienced an improvement in their quality of life-based on MIQ (Menorrhagia Impact Questionnaire) scores2, 91 percent of patients were very satisfied or satisfied with the procedure3, and 93 percent said they would recommend it to a friend.3 Sustained results were reported three years after treatment.3

About Heavy Menstrual Bleeding (Menorrhagia)

Many women experience heavy menstrual bleeding at some point in their lives. One in three women seek treatment for heavy menstrual bleeding.1 Healthcare professionals call this condition “heavy menstrual bleeding (HMB)” or “abnormal uterine bleeding (AUB)” or “menorrhagia”. The increase in quantity and duration of menstrual bleeding can negatively impact a woman’s physical, social and emotional well-being, and can make it difficult to engage in activities such as work, family care, exercise and sex.
